INCUBATOR.

Application filed October 3, 1921. Serial No. 565,033.

To all whom it may concern; I Be'it known that I, \VILLIA J, Sorrrnv- KnL, Jr., a citizen ofthe United States,.residing at Brookville, in the county of Franklin and State of lndiana have inventedcertain' new and useful2 Improvements in Incubators, of which the following is a specification- This invention relates to incubators and the primary object of the invention is to; provide an improved incubator embodying a novel heatin'grneans', which is so; constructed that the incubator" will is be evenly heated, without the entrance of any fumes or obnoxious vapors from the v heating means. The air supplied to the. incubator is taken exteriorly of the heating means but heated by said means, thereby insuring the entrance of fresh warm air into the incubator, whichis so necessary to the proper incubation of the eggs.

Another object of the invention is to provide a novel means for constructing the body portion of the incubator, wherebythe best results can be, obtained therefrom, and whereby the heat radiating pipeycan be readily exposed to view, and readily connected to or disconnected from the heating plant or device.

A liirther object of the invention to provide an improved incubator of: the above character, which will be durable, andeflicient one thatwill be s mple and easyto at, and one which canjbe placed upon the net at a mininnun cost,

Another object of the invention is to "pro ll ith these and other objects in view, the

cal section through a portion of the incubator taken on the, line 22 of Figure 4, illustrating the novel heating plant carried thereby. V j a Figure 3 is a detail transverse sectional view through :the heating plant, taken on the line 3 3,of Figure-2.

i Figure eisla fragmentary section through the incubator take non the line 4 of Figure ,2, illustrating the novel heating plant, and expansion tank thereof, of the vincubator. Figure 5-iis a fragmentary horizontal section through 3 the incubator showing the means of arranging tliehot water heat radiator pipe therein, and the warm air distributap p 1 dfigui'e 6 is a transverse vertical section through the improvediincubator.

Figure 7 is a fragmentary vertical section through the incubator showing the novel means of associating the heating lamp with the incubator.

Referring to the. drawings in ,detail, wherein,similar reference characters designate corresponding parts throughout the severalviews, the letter A indicates the incubator proper B, thenovel heating plant therefor and C, the-novel-lmeans of controlling the fiow of ;.hot, air through the heating means and the warm air from the incubator. I

The incubator Aniay be of any desired size for incubatingthe desired number of eggs and may contain one or more trays 10 for receiving the eggs. 'As shown in the drawings, thezincubator, is ofa size for receiving two of the trayslO, but in forming anincubator for asingleitray, substantially thefsame form ofincubator and heatingmeans would be carriedout. The

incubator A; includes the-main body per Lion-:15, which may be supported by corner legs 16,.-of ,the desired form and construction. vThe body portion of theincubatorA includes the front wall 17 the rear wall 18, the end wallslQ, the bottom Wall 20, and the top WEtllQl. These walls 18 19, 20,

and 21 are preferably formed with two spaced skins22 and23, ofuthe desired material, and the spaces, intermediate the skins are filled with somev suitable ,.non heat conducting material 2a, The top wal'l'Ql is preferably formedas a single unit, so that itl can bereadilycremoved to exp ose the interior of the body portion 'of the incubator A. for a, purpose whi h will here 'm down on its hinges 47 and then the inner doors 41 are. swung downward on their desired fOnelend wall19 of the body 15 of. the incubator A is adapted to support the" ble cleats or guides 27'.- These trays 10'consist of an upper rectangular frame 28 and a lower rectangular frame 29, between which is adapted to be positioned andheld' the wire screen 30 upon which the eggs are adapted to rest. The lower frame 29 carries" suitable supporting cleats 31 for preventing the sagging'of. the wire screen 30.

The frames 28 and 29 can be constructed in any preferred manner in orderthat a rigid and cheap construction will be had. The front'wall 17 consists of spaced lowerand upper. longitudinally extending cleats and 35, and inner spaced upper cleats 37.

The cleats 35 and 37 are joined by a 1011- gitudinally extending stop strip 38 and the space between-the cleats 37 and 35 may be filled, if so desired, with some suitable nonheat conducting material similar to the material 24. The outer lower cleat, 34 supports the outer longitudinally extending door 40, while thelower wall 20 inwardly of thecleat 34, hingedly sup-ports a pair of doors, 41, which are adapted to close the twocompartments defined by the central partition .26 and these doors 41 are providedfwith glass panels 42. The outer longitudinally extending. door 40, is provided in front of thedoors41 with transparent panels 43, and these panels are normally closed by hinged swinging plates, 44. As shown, these plates 44m hinged uponpins 45, and are held against swinging movement'at their lower ends by resilient clips 46." It can be seen that when it is desired to look into the compartment'and see the eggs" on thetrays 10,- it is merely necessary to swing the 1 plates 44 ,on'theirpins 45 and glance through the panels 43 and 42. VVhen it is desired to remove the trays, the front door 40 is swung hingesi- The atom c and4'1 nay be held closed by suitable pi-voted latches 48 if so heating plant B and this wall is suitably treated to receive theiframe, as will be more fully'described. It "can be seen, however,

that this'wall '19. is provided with an inwardly extendingopening 50 and the outer skin ofthiswall 19 is recessed. as at 51 for receiving a portion iof'the heating plant and for forming aseat. herefor, as will'be hereinafte 'more' fully apparent. v V,

The heating plant" B comprises the inner aziarh e s t men s aI e w hot water chamber 53. This chamber 53is provided with an inwardly extending integral lateral enlargement" 54, which constitutes the main portion of the hot wa-. ter heating plant or. boiler. Thelaterally extending compartment 54 has provided extending longitudinally therethrough a relatively large hot air heating fiue' 55,

which extends at right angles'to the main vertically disposed heating fine 52. and ex tending through the laterally extending hot air heating fine 55 is a plurality of hot water heating tubes 56, which communicate with the upper and lower portions of thelaterally extendinghot water compartment54, and it can be seen that the hot vapors arising through the flue 52'will flow through the laterally extending hot air flue 55 andaround. the hot water tubes 56,. The hot water chamber and laterally extending compartments 53 and 54 are surrounded by an'outer wall 57, which has opening,,into v the same the laterally extending hot air flue 55 and the hot vapors are adapted to 'fiow into the space designated by the numeral 58 between the outer wall 57 and th'e walls defining the.

hot water-compartment 53 and the laterally extending chamber 54/ The rear end'of the wall 57 surrounding the hot water chamber 53 and the compartment 54 is provided with laterally extending extensions 59 defining an opening 60through which the hot vapors are adapted to flowinto the atmosphere after circulatingaround the hot water compartment53 and chamber 54. It can be seen that by referring to Figure 3 offthe drawings, top and bottom walls 61 and 62 are provided, which close the-upper ends of the space. 58. defining the hot air circulating space and the hot water chamber and compartment. A second wall 63 is disposed around the heating chamber in spaced relation to the wall '57 defining a warm all space,

64, which communicates with an inwardly extending warm a r p1pe65 which 1S'Cl1S- posed through'theopening 50. The wall 63 and the whole heating plant is enclosed by a suitable casing 66 of non-heat conducting material, and this casing 66 has the top and bottom walls 67 and 68 thereof provided with openings69 to permit. the entrance of fresh air into the warm air space 64 and air into the flue 52 and to permit the chimney .70

of the heating lamp 71 to extend into the,

main flue 52. The chimney 70 may be of the desired shape or configuration and is adapted 'tobe detachably fitted on the heating lamp 71'. The heating lamp71 may be ofany de-' sired character, and as shown includes the fount 7 2 for receiving the oilor other burning fluid and this fountis'provided with a suitable burner. The, fount 72 can be de tachably fitted upon a supporting base 73,

which is carried by a bracket 74.

portion 15 of the incubator.

7 rom this construction, it, can be :seen that the inc'ubator is not only eliectively heated in an efficient and cleanly manner, but that a sufiicient quantity of warm fresh r v 1 means including a radiator dlsposed within air is 'supplied thereto.

' 3 If desirable, the end; Walls 19 may pro yided with openings lOliand these openlngs can ,be'covered by suitable light pro- .tecting hoods 102 carried by the outcrfsurface ot'the end walls 19.

When the incubator becomes heated to the desired temperati'ire, the damper 95hwill be operated' by the" thermostat in, the usual manner and beliited from off of its seat, permittingthe escape of the hot vapors directly from the flue 52 and escape of the warm air from the incubator. a

It is apparent, of course that the distance the damper 95 is lifted from off of its seat, regulates the amount of hot and! heated air 52 and fromthe body portion of the incubator. i

nected to an outlet pipe nanma exe tend exteriorly of the body portion '15 of the incubator. This pipe maybe provided with a suitable pet cock 111. This pipe will permit' the escape of air ifthe same becomes.

trapped in thesystem, and maybe usedit'or desirable.

From the foregoing description, it can be seen that an improved incubater has been provided, of exceptionally simple and the incubator and a novel means ior sup-,

durable construction, ,which embodies a novel hot water heatlng means for heating plying fresh-warm air to the interior of the incubator.
